Gregory W.

Incredible experience with HRC waterproofing. After three basement floods over 10 years we reached out to HRC and Raymond and his team (on short notice) put in pumps and a French drain. Our basement has stayed dry through several severe storms in which our neighbors experienced flooding.

Ryan L.

HR installed a french drain system in my basement a few months ago. The system has kept my once flooded basement dry as bone. I no longer have to worry and watch the weather wondering not if, but how much water I will get.

Michael S.

The team was very professional and well versed in waterproofing. They provided multiple solutions at a fair price and didn’t pressure me into any additional services. In the event it’s needed I’d use them again.

FAQ's

  • What exactly is interior waterproofing, and how is it different from exterior waterproofing?

    Interior waterproofing focuses on managing water that has already entered or is entering a basement or crawl space. It involves installing drainage systems, sump pumps, and vapor barriers from inside the home. Unlike exterior waterproofing, which often requires excavation, interior solutions are less invasive and more cost-effective in densely built areas like New York City where exterior access is limited.

  • Why does my basement leak even though there are no visible cracks in the walls?

    Water can seep through porous concrete or cinder blocks, not just cracks. Hydrostatic pressure builds up in NYC’s water table, pushing moisture through walls and floors. In some cases, condensation or plumbing leaks also contribute. HRC Waterproofing uses specialized moisture detection equipment to pinpoint hidden leaks and design comprehensive solutions tailored to the unique foundation conditions of your property.

  • Will interior waterproofing eliminate all mold and mildew in my basement?

    Interior waterproofing creates a dry environment that prevents new mold growth, but it doesn’t automatically remove existing mold. HRC Waterproofing offers mold remediation or can work with mold specialists to ensure your space is not only dry but also healthy. Proper ventilation, dehumidification, and sealing are key steps in creating a lasting mold-resistant environment.

  • Is a sump pump necessary in every interior waterproofing system?

    Not always. It depends on the severity of your water intrusion and the drainage strategy used. In low-lying areas of NYC with high groundwater or frequent flooding, sump pumps are often essential. HRC Waterproofing evaluates your basement’s grade, water entry points, and drainage options before recommending a sump pump. If installed, they also include battery backups to prevent failure during power outages.

  • How long does it take to complete an interior waterproofing job?

    Project timelines vary based on basement size, the severity of the water issue, and the type of system installed. Most interior waterproofing jobs are completed in 2–5 days. HRC Waterproofing ensures minimal disruption by carefully scheduling phases and cleaning up thoroughly each day. Clients receive a clear project timeline upfront with daily progress updates.

  • Will interior waterproofing raise my property value in New York?

    Yes. A dry, usable basement increases livable square footage and adds to your property’s appeal in NYC’s competitive real estate market. Many buyers view waterproofed basements as a premium feature, especially in older buildings where water issues are common. HRC Waterproofing provides transferable warranties, which are an added selling point for future buyers.

  • What happens if I ignore a basement water problem?

    Delaying waterproofing can lead to serious structural damage, mold growth, rotting wood, and ruined possessions. Over time, unchecked moisture can deteriorate foundations and reduce indoor air quality. In NYC’s humid, flood-prone climate, these problems escalate quickly. Early intervention by HRC Waterproofing can prevent thousands of dollars in future repairs and health risks.

  • How can I tell if my basement water problem is from condensation or seepage?

    Condensation often forms on cold surfaces (like pipes or walls) and occurs during humid conditions. Seepage leaves wet patches on walls or puddles near the foundation, even during dry weather. HRC Waterproofing conducts a thorough inspection using moisture meters and thermal imaging to identify the source and customize the right waterproofing plan.

  • Can interior waterproofing stop water from coming up through the basement floor?

    Yes. This problem, known as hydrostatic pressure, is common in areas with high water tables like NYC. HRC Waterproofing installs sub-floor drainage systems, including French drains and sump pumps, to relieve pressure and redirect water away before it can rise. These systems are discreetly installed under your floor slab, with minimal impact to the space.

  • Is interior waterproofing disruptive to my daily life or living space?

    Interior waterproofing is designed to be minimally disruptive. HRC Waterproofing uses dust containment barriers, proper ventilation, and daily cleanup to maintain a safe and livable environment throughout the project. Most work is done in basements or crawl spaces, allowing homeowners to continue their routine uninterrupted in the main living areas.
